package/libcamera: fix uclibc/musl compile with libexecinfo enabled

Browse Source 
- depend and link against libexecinfo if enabled to fix linking failure
  in case execinfo.h is detected, see
  libcamera-40f5fddca7f774944a53f58eeaebc4db79c373d8/meson.build:

   32 if cc.has_header_symbol('execinfo.h', 'backtrace')
   33     config_h.set('HAVE_BACKTRACE', 1)
   34 endif

- libexecinfo already depends on !BR2_TOOLCHAIN_USES_GLIBC

Fixes:
